- hey guys i setup 3 NIC in our UBUNTU eth0 is configured for our DSL internet connection eth1 is configured for our LAN and uses 192.168.0.1. our windows networks uses 192.168.0.2 and so on... i installed a 3rd NIC in our UBUNTU and uses 192.168.0.36 and so on for a second windows network. Both eth1 and eth2 are different windows network. may goal here is to use the UBUNTU linux to access files from both different networks. but there is a problem i use 192.168.0.40 in the eth2 interface and tried to ping 192.168.0.36 but an error shows up saying not permitted. then other problems was experienced the contents of the UBUNTU network servers can be displayed and computers using the eth1 as gateway to the internet can no longer access the net.pls help me out here:sigh:

I was trying to see if eth1 and eth2 had ther correct drivers and were configured properly. Since the DSL connection works, that will tell whether eth1 and eth2 work when used on those.

this is probably more of a network issue than a linux problem....
could you be more specific about the IP addresses and their subnet masks?
if you have a 192.168.0.1/24 (or 192.168.0.1/255.255.255.0), then you shouldn't assign another network card in the same 192.168.0.x range. Try putting the other side of the LAN on a 192.168.1.x range and see what happens.
